HOLDING MEANSFOR ATTACHMENTS FOR SEWING-MACHINES.

Specification of Letters Patent.

Patented Sept.9, 1913.

Application filed December 30, 1910. Serial No. 600,133.

To all whom it may concern:

Be it known that I, BENJAMIN FLOUR- TIs, a citizen of the United States, residing at Govington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Holding Means for Attachments for Sewing-.Ma-

chines, of which the following is a-specifica tion.

My invention relates to holding means for attachments for sewing machines.

The object of my invent-ion is toprovide means on attachments for sewing machines, such as seam-binders, hemmers and the like for holding said attachments steady and prevent them from sliding and coming into presser-foot as they so often do now.

-My invention is shown mounted upon a seam-binder attachment, this particular attachment being used to a great extent in factories making garments;

It has been found that the set-screw or thrunb-screw which has been provided to secure the seam-binder or attachment to the bed-plate of the sewing machine has been insuiiicient to hold the seam binder properly, inasmuch as the constant vibration of the machine in operation causes it to, work loose and alsothe operator very oft-en engages or strikes the end of the seam binder and works same loose, allowing it to swing using the thumb-screw as a pivot'and invariably bringing the end of the seambinder into contact with the bifurcated presser-foot. This is done so often that the end of the seam binder becomes dilapidated and worn out.

On account of the vast number of scam binder attachments used in factories manufacturing garments, and owing to the carelessness of the operators, firms require their employees to furnish their own seam-binder attachments, the expense being too great to justify them in furnishing said attachments. Thus it is seen that great advantage is derived from my device, which may be readily attached to seam-binders, said device being inexpensive to manufacture, simple in construction, and durable in use.

By placing my improved holding device upon the attachment the life .of said attachment is prolonged indefinitely, and will absolutely prevent the end of the seambinder from engaging the presser-foot and equipped with my invention.

turn-out the work properly.

Very often the seam-binder attachments are thrown out of alinement due to the loosening of the thumb-screw and thereby cause the seam to be irregular. My invention, however, insures a uniform seam to be produced at all times, and absolutely holds the attachment firmly in position.

- In the accompanying drawing which serves to illustrate my invention: Figure 1.

is a perspective view of a fragment of the will always be held in proper position to base plate of a sewing machine having a seam binding attachment which is detail view ofmy holding device which" is adapted to be mounted upon the attachment. Fig. 3 is a fragmentary view of the base plate of a sewing machine showing where the devices are adapted to be placed and'fastened. -Fig. 4: is a plan view of a seam binding attachment equipped with my "device, the attachment being shown mounted upon a fragment of the base plate of a sewing machine. Fig. 5 is a side elevation of a seam-binder attachment'equipped with my invention. Fig. 6 is a side elevation showing a modificatiom'and Fig. 7 is an end elevation of the seam binder. 7

Referring more particularly to the drawing, 1 illustrates the bed plate of a sewing Fig. 2'is a In nearly all of the feed cover plates 2 a hole 8 is provided for the purpose of securing some special attachment to the machine. Taps 9 are provided in the bed plate 1 for receiving a thumb-screw 10, which is intended to hold the seam binder attachment 11. v The seam-binder 11 is of the usual construction having a guide and support flange 12 thereon and a hollow curved neck 13 in which the seam-binding strip passes. The straight end of the hollow neck of the seam binder tapers or converges, the inner edges of which turn under to form the seam binding strip of material in the proper shape for binding the garment desired, as shown in Fig. 6.

An arm 14 having a slot 15 therein is provided on said seam-binder 11 and is adapted therefore provide an arm 17, which is adapted to be riveted'on the extension 14 of the seambinder 11. The arm 17 is provided with a downwardly extending portion 17 wvhich is provided with a point. It is the downwardly extending portion 17 which is adapted to enterthe holes in the feed cover plate 2. The outer end of the arm 17 may be bent if necessary to cause the downwardly extending portion to properly engage the hole 8. Thus the arm 17 being firmly fastened to the seam-binderll and accurately engaging the hole 8 in the cover plate, it is readily seen that incombination with the thumb screw holding device 10 that the seam-binderwill be firmly held in position, and cannot possibly swing to right orleft. It will be understood that if the hole 8 is not in proper position or if no hole is provided, a hole may be drilled in theplate 2 at the proper position.

My device serves as a guide for placing the attachment in accurate position for use, and maintains it in such position "after it is so placed and clamped by the thumb screw 10, thus affording an accurate guide for insuring absolutely the proper and accurate position oftheattachment for use. The cheapness of my invention and the The thumb-screw v ment.

made, such as changing the shape of the particular holding device and fastening it at a diiierent point upon the attachment,

and I do not wish to be confined to the exact details shown;

If desired, my device may be made adjustable by providing a boss 18 on the seambinder 11 and providing same with a slot 19 which the arm orholding device 17 may enter. Theboss then may be provided with a set-screw 20 which bears against thehold ing device 17' and clamps it to said attach- In this manner the holding device may be adjusted to any position.

What I claim as new and desire to secure by Letters Patent is In a seam-binder. attachment for sewing machines having a slotted arm thereon provided with a set-screw extending through said slotted arm and adapted to clamp said arm to the-bed-plate of a sewing machine,

a rigid arm riveted on said seam binder attachment at right angles to said slotted arm, and a turned down portion at the end of said rigid arm adapted to enter'a hole in the bed plate of a sewing machine and prevent movement of said attachment, substantially as set forth and for the purposes specified.
